“In this article, we will be looking once again to lessen the burdens of every day life by automating some of the tasks which take up our precious time. We will be using Cron, a time-based job scheduler in Linux to periodically run scripts to do things we would normally have to do manually.”

“Now the real fun begins. Even though the Hexbug’s motion is limited, with the addition of a few simple sensors and some clever programming, it can do remarkable things. For example, a right turn is accomplished by doing a reverse turn for about 2 seconds. How can it make a left turn? Simply do a right turn for 6 seconds – 3 right turns equal one left turn.”

“This thing may remind you of an Arduino but it’s not, it’s not even an AVR but a dsPIC30F2012. Lots of times I want to try out something, but I’m too lazy to make the whole thing over and over on a breadboard so why not solder it together quick on a pref board so I can just stick it in. And always too lazy to put on RS232, but it’s a great debug so that’s why it’s on the board, actually it’s the only feature that’s built in to the board, because its really the only thing I need.”

“Only recently I’ve found the time to expand my old project in the most obvious way possible; by adding 3 more buttons to these IO ports and thereby creating a 4-key-keyboard, without having to add any other hardware than these 3 extra buttons.”

“Alex Weber over at Instructables built a great programmable LED based on the AVR chip. Since I am tooled for PIC, I thought it would be fun to replicate what he has done. This simple project is fun and it provides a great building block for playing with collective behaviors.”

“In the quest to relieve perpetually tense forearms due to bouldering + heavy keyboard usage I came up with this massager using easily obtained components. The total parts list with estimated price: (all items except for skateboard wheels were obtained at Lowe’s).”

“The oscilloscope simulation shown on this website is based on the HAMEG HM203-6 20 MHz oscilloscope of Hameg GmbH in Frankfurt/Main, Germany. The HAMEG HM203-6 oscilloscope only was the inspiration for developing the simulation, because it is very well suited for this purpose.”

“In this article, we will once again be using the magic of software to enhance our lives. We will be using a technique known as web scraping to gather weather information to prepare for whatever mother nature throws at us. This could be useful if you live in a suburb and must commute some distance to work in the city.”

“Last month I talk about Remote Controlled Mobile Robot using MC40SE, this month I want to use it for simple line following robot…The list of hardware needed: MC40SE board, LINIX Brushless Motor, 2 x 4” Nylon wheel, 2 x 12V battery, 4 x fiber optic sensor and a robot base which mounts with a castor and brushless motor properly.”

“Question: What makes 8 times ‘beep’, but cannot be heard?
Answer: My ultrasonic range finder 🙂 ~ FRDM-KL25Z with HC-SR04. What I’ve added to my FRDM-KL25Z board is an ultrasonic distance sensor, measuring distances up to 4 meters.”

Don’t miss this thorough tutorial on using and interfacing ultrasonic range finders to microcontrollers.
